ORGANOSILICON FRAGMENT MODIFIED PHTHALONITRILE MONOMER, METHOD FOR PRODUCTION THEREOF, BINDER BASED THERON AND PREPREG Russian patent published in 2016 - IPC C08G77/26 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of producing modified phthalonitriles containing silicone fragments, and binding materials based thereon. Disclosed is an organosilicon fragment-modified phthalonitrile monomer of general formula I, where X is a divalent aromatic radical selected from a group comprising and Y - silicone fragment selected from a group comprising -SiR¹R² and SiR¹R²-O-SiR¹R², where R¹ and R² - radicals selected from a group comprising CH₃, C₆H₅, and HC=CH₂. Also disclosed is a method of producing disclosed phthalonitrile monomer, binder based thereon and prepreg.

EFFECT: disclosed phthalonitrile combines properties of traditional types of phthalonitriles - high heat resistance - with advantages of organosilicon polymers having good solubility, preservation of heat resistance, low glass transition temperature providing aggregative state at room temperature in form of viscous liquid or semisolid substances.
